Abstract
The invention relates to a novel air grid structure for a box fan. Rotary shafts at both ends of an air grid are arranged on a large circle and a small circle outside and in the middle of an air grid frame respectively; a center shaft is arranged and fixed on the small circle in the middle of the air grid frame and is vertical to the plane of the small circle in the middle of the air grid frame; teeth in bevel gear shapes are fabricated at the circumference of an outer circle of an adjusting knob; and the adjusting knob is arranged on the center shaft through an outer circle hole in the middle of the adjusting knob. In addition, the teeth on the adjusting knob are engaged with teeth on the air grid, and a fixing knob is arranged on the center shaft at the upper part of the adjusting knob.
Description
Technical field
The present invention relates to a kind of structure of rotating vane pectinid grid, particularly a kind of structure of novel rotating vane pectinid grid belongs to household electrical appliance technical field.
Background technique
The rotating vane fan makes the people can feel comparatively comfortable sensation, still because its air grid can change turning to of wind that electric fan blows out; Present rotating vane pectinid grid; The angle of its air grid is changeless, so, the also just fixing inconvenience of its wind direction, power; So, bring certain restriction for people's selection.
Summary of the invention
The objective of the invention is to: a kind of structure of novel rotating vane pectinid grid is provided, and the angle of its air grid can change arbitrarily, can change its wind direction, power arbitrarily, satisfies people to wind direction and strong and weak more more options.
The present invention realizes that the technological scheme that above-mentioned purpose adopts is: a kind of structure of novel rotating vane pectinid grid; It is to be installed in respectively on the outside great circle of air grid frame on the roundlet with the centre by the rotating shaft of air grid through its two ends; Axis is fixed in the middle of the air grid frame on the roundlet, and vertical, produces the tooth of umbrella gear shape on the circumference with the adjusting knob cylindrical with little disk in the middle of the air grid frame; Adjusting knob is installed in above the axis through the outer circular hole wherein; Simultaneously, its tooth and tooth on the air grid on one's body forms meshing relation, fixed knob is installed on the axis on adjusting knob top.
Beneficial effect: the present invention is because through loosening fixed knob; The rotation adjusting knob, then because tooth on the adjusting knob and the tooth on the air grid form meshing relation, so; All air grids are just interlock rotation also; Change the angle of air grid, thereby reach its wind direction of any change, power, satisfy people wind direction and strong and weak more more options.
Description of drawings
Below in conjunction with accompanying drawing structure of the present invention is described further.
Fig. 1 is the assembling relationship figure of air grid and air grid frame.
Fig. 2 is the A-A sectional view of accompanying drawing 1.
Fig. 3 is the B-B sectional view of accompanying drawing 2.
Fig. 4 is the profile of tooth figure of adjusting knob.
Shown in the figure: 1, air grid frame; 2, air grid; 3, adjusting knob; 4, fixed knob; 5, axis.
Embodiment
The rotating shaft of air grid 2 through its two ends is installed in respectively on the outside great circle of air grid frame 1 on the roundlet with the centre; Axis 5 is fixed in the middle of the air grid frame 1 on the roundlet, and vertical, produces the tooth of umbrella gear shape on the circumference with adjusting knob 3 cylindricals with little disk in the middle of the air grid frame 1; Adjusting knob 3 is installed in above the axis 5 through the outer circular hole wherein; Simultaneously, its tooth and tooth on the air grid 2 on one's body forms meshing relation, fixed knob 4 is installed on the axis 5 on adjusting knob 3 tops.
Claims (1)
1. the structure of novel rotating vane pectinid grid; It is characterized in that: the tooth that produces the umbrella gear shape on the circumference of adjusting knob (3) cylindrical; Adjusting knob (3) is installed in above the axis (5) through the outer circular hole wherein, and simultaneously, its tooth and tooth on the air grid (2) on one's body forms meshing relation.
